its the saito,the ys hasent turned up yet,but i like this combination at the moment.im curently flying with cg slighty tailheavy but the 3d is ausome like this just crap on other things.does a seriously tight waterfall and tourqe rolling etc is ausome,but flying it today in slight wind wasnt to good for the rear weight ,harrier crawls were nosing up to much even on tick over sometimes.gonna move bat more forward though for next time.
